Voltage/Reactive Power Requirements Clause Samples
The Voltage/Reactive Power Requirements clause sets out the standards and obligations for maintaining specific voltage levels and reactive power at a facility or point of interconnection. It typically details the acceptable voltage range and the required reactive power support that must be provided by the generating facility or equipment, often referencing grid codes or utility requirements. This clause ensures that the facility operates within parameters that support grid stability and reliability, preventing issues such as voltage fluctuations or power quality problems.
Voltage/Reactive Power Requirements. Electricity generated by the Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 hertz (nominal) alternating current at the normal operating voltage of 69 kV. The actual operating voltage will be determined by the Company.
Voltage/Reactive Power Requirements. The Facility shall have compound sources of power for its excitation system so that, in the event of a Company System fault, the Facility’s generator field does not collapse.
Voltage/Reactive Power Requirements. Electricity generated by the Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 Hertz alternating current at a nominal operating voltage of 69 kV. The actual operating voltage will be determined by the Company. Reactive kVAr requirements will be from 0.90 leading to 0.85 lagging power factor delivered by the Seller to the Company. The Facility generators must be capable of automatically adjusting reactive control to maintain the bus voltage to meet the target specified by the System Operator. The target will be specified remotely by the System Operator through the EMS. The generators should not normally operate on a fixed var or fixed power factor setting except during startup or shutdown or if agreed by the Company. The Facility shall have under-voltage and over-voltage ride through capability. The Facility shall behave as follows during under-voltage disturbances and over-voltage disturbances (“V” is the voltage of any of the three phases at the Point of Interconnection):
Voltage/Reactive Power Requirements. (a) Electricity generated by Seller shall be delivered to the Company at the Point of Interconnection in the form of 3-phase, 60 hertz (nominal) alternating current at the normal operating voltage of 69 kV. The actual operating voltage will be determined by Company.
(b) The Facility must deliver power up to the Firm Capacity at a power factor between 0.90 lagging and 0.95 leading to the Company System. The Facility generator must be capable of automatically adjusting reactive control to maintain the bus voltage at the Point of Interconnection to meet the scheduled voltage set point target specified by the Company System Operator. The voltage target will be specified remotely by the Company System Operator through the SCADA/EMS. The Facility’s voltage set point target must reflect the Company voltage set point target issued from the SCADA/EMS, without delay. The generator should not normally operate on a fixed var or fixed power factor setting except during startup or shutdown or if agreed by Company. The voltage setpoint target, and present Facility minimum and maximum reactive power limits based on the Facility real power export and the unit capability curve shall be provided to the Company EMS through the RTU telemetry interface.
(c) The Facility shall have under-voltage and over-voltage ride through capability. The Facility shall behave as follows during under-voltage disturbances and over-voltage disturbances (“V” is the voltage of any of the three phases at the Point of Interconnection). For alarm conditions the Facility should not disconnect from the Company System unless Seller reasonably determines based upon Good Engineering and Operating Practices that the Facility’s equipment is at risk of damage. This is necessary in order to coordinate with the existing Company System: V ≥ 0.80 pu The Facility remains connected to the Company System in continuous operation. 0.00 pu ≤ V < 0.80 pu The Facility remains connected to the Company System and in continuous operation for a minimum of 600 milliseconds (while “V” remains in this range). The Facility may initiate an alarm if “V” remains in this range for more than 600 milliseconds; the duration of the event is measured from the point at which the voltage drops below 0.75 pu. and ends when the voltage is at or above .75 pu. The 600 milliseconds represents a delayed clearing time of 30 cycles plus breaker opening time.
